Anybody know any good cardio exercise videos?

I'm looking to do around 45 minutes of cardio everyday to make me tired. I'm mainly doing this to get a better night's rest as well as improve cognitive functions. I don't exercise at all and I'm still in decent shape (not overweight). I'm looking for a free YouTube video or something of the sort so I can do these 45 minutes of cardio everyday. I'm looking for something that's not too easy but not too hard either. Enough to make me tired and sweat.

Thanks.

 

you should do hiit, this will get you tired 100%

 

Nothing is better than running for cardio exercises. Try jogging a mile or two. This will significantly increase your stamina as well.

 

I was actually going to do this, however, it's way too cold to go outside at the moment where I live so I wanted to do cardio in my living room instead. I'll definitely start running when it gets warmer.

 

I've been working out for over 4 years, I suggest you start going for a walk before any kind of running. Running is very tough and disciplined.

edit: Hiit will feel like a military boot camp if your up for it.
